post-stroke BBB disruption
Defect of the blood-brain barrier after stroke shown in MRI. T1-weighted images, left image without right image with contrast medium administration.

A few days old right superiofrontal cortical cerebral infarction. The left image (DWI) still shows a clear diffusion disturbance. The right-hand image (T1 with gadolinium contrast) shows the seam-like contrast agent enrichment as a sign of blood-brain barrier disorder. A haemorrhage was also visible in a T1 without contrast.

Temporal changes in blood–brain barrier permeability and cerebral perfusion in lacunar/subcortical ischemic stroke. BBB-PS maps in a patient with a subcortical infarct in right putamen (as shown on the 3-month NECT). The maps from acute phase to 3 months after stroke were shown. Focally elevated BBB-PS was observed in right putamen at 24 h, day 7 and month 3 for the patient. Caudate nucleus, putamen, globus pallidus and thalamus in both ipsilateral and contralateral hemisphere were outlined in red. The infarct in the right putamen shown on the 3-month NECT was also outlined in red (smaller ROI within the right putamen)
